AVOID BUYING THIS. I bought this 3 weeks ago and was very disappointed. This does NOT work with flash carts, game compatibility isn't great (Super Mario Brothers 3 doesn't work) and sound accuracy isn't great. The only saving grace is the HDMI. I also wrote an Amazon review about this. Here's my YouTube video if you don't believe me. Just wait for the Super Retro Trio HD, whenever the hell that comes out. If you REALLY want it, get it from Amazon right now for the fast Prime shipping so you don't have to wait here on Massdrop.
